Title: Improvements in or relating to built-up crankshafts for reciprocating engines
IPC: F16C3/12
Filed: 1932-12-29
Abstract: 398,380. Crankshafts. BELYAVIN, P., 2, Tennyson Mansions, Queen's Club Gardens, Kensington, London. Dec. 29, 1932, No. 36732. [Class 80 (ii).] For removably securing the crank pin A, Fig. 2, and/or the journal pin B in the web G of a built-up crankshaft, the web is formed with slots E, F which render the inner part H of the web flexible. The slot E is expanded by a wedge or screw C, thereby tightening the web on the 'pins. The periphery g of the web is of sufficient strength to resist the compressing force exerted by the wedge. Dowel pins d may be employed. K is a balance weight. In modifications, various arrangements of the slots E and wedges and/or screws C are described. In one, the slot F does not extend completely between the pin sockets. In another modification, Fig. 14, a slot extending inwardly from the periphery of the web is expanded by wedges or screws. Fig. 17 shows one arrangement of a wedge C. This is drawn into guides c in the slot E by a screw D. Fig. 21 shows the use of a double conical wedge.

Abstract: 1490382 Frequency modulation receivers R BOOTH 9 Sept 1975 [9 Sept 1974] 37032/75 Heading H3R An FM receiver with means for increasing the frequency deviation representing the modulation signal comprises a first signal channel 17- 27 for demodulating the incoming modulated carrier signal, a second signal channel 33-47 including a mixer 36 connected to receive the output of a controlled oscillator 37 frequency modulated by the demodulated output of the first channel in such a manner as to produce frequency deviation 180 degrees out of phase with the frequency deviation of an incoming carrier signal applied to a second input of 36.

Patent GB-1405936-A (GB)
Title: Coin selector
IPC: G07D5/00
Filed: 1972-08-09
Abstract: 1405936 Testing coins MARS Inc 9 Aug 1972 [16 Aug 1971] 37227/72 Heading G4V A coin tester comprises a coin passageway 12, first and second coin presence sensors spaced apart in the direction of movement of the coin, means 20 for generating a magnetic field upstream of at least one of the sensors, means for measuring time intervals dependent on coin presence sensing by said sensors and means for comparing the measured time intervals with predetermined standards. In the four denomination tester described there are two secondary sensors 44, 46, preferably phototransistors, located upstream of a primary sensor 42. The sensors are arranged so that a 50 c piece will obscure all three sensors simultaneously, a 25 c piece obscure all sensors but only sensors 42, 46 simultaneously, a 5 c piece obscure sensors 42, 46 simultaneously but not sensor 44 at all and a 10 c piece obscure only sensors 42, 46 but not simultaneously. Obscuration of sensor 44 sets a flip-flop 56, reset by coin arrival sensor 28, to apply an input signal on lead 66 to gates 48, 50 associated with 50 c and 25 c pieces respectively the other inputs to these gates being from sensors 42, 44 and 46 either directly or via inverters. The other output 76 of flip-flop 56 is applied as an input to gates 52, 54 associated with 5 c and 10 c pieces respectively these gates also being connected to the sensors and having another input 84, 86 from a flip-flop 58 which is set when sensor 46 is obscured indicating that the coin is of a minimum permissible diameter. According to the diameter of the coin the input conditions at one or none of the gates will be met, the time interval during which such conditions are met being dependent on the diameter and velocity (and hence due to the eddy current braking effect of magnet 20 on the electromagnetic properties) of the coin. The outputs of gates 48, 50, 52 and 54 are connected to gate 94 and also as enabling inputs to respective flip-flops 102, 104, 108 and 106. The output of gate 94 acts via gate 116 to allow pulses from clock generator 114 to pass to counter 112 which is connected to a decoder 110 having four pairs of outputs, each pair corresponding to the lower and upper expected count levels for one denomination of coin and being connected as enabling and disabling inputs respectively to the appropriate flip-flop 102 to 108. If the coin is acceptable with regard to its diameter and velocity the corresponding flipflop will be set, the outputs of the flip-flops being connected to a coin acceptor 122 and a pulsemaker 124 that provides a number of pulses corresponding to the denomination of coin to an accumulator 126. The pulsemaker is blocked until the coin no longer obscures sensor 42 thus ensuring that the velocity examination is complete and may also be blocked by a high price signal on lead 132 from the accumulator, a similar high price lead 134 serving to render the acceptor 122 inoperative. The secondary sensors may be located downstream of the primary sensor.

[Also in Division H4] A nodding aerial 1 is oscillated about an axis 2 by mechanism comprising a differential lever 9 having a central pivot-pin 8 which is connected by tie rods 4, 5 to points 6, 7 on the aerial 1, the ends of the lever 9 carrying pivotpins 10, 11 which are oscillated from a common drive source. Pivot-pins 10, 11 are connected by links 12, 13 to eccentric pins 14, 24 on rotary members 15, 16 respectively which are connected by worm and wheel gearing with shafts 19, 20 which are driven through a differential gear-box by an electric motor 23. By means of a handle 22, adjustment may be effected between limits in which the pins 14, 24 are either in the same straight line, causing maximum nodding oscillation of the aerial, or they are diametrically opposed, in which case no nodding oscillation occurs. Rotary members 15, 16 are mounted in a support member 17 which may be raised or lowered to vary the position of the horizontal axis about which the aerial oscillates.

Abstract: 365,264. Brake bands and shoes. CLARK, S. C., Pontiac, Michigan, U.S.A. Dec. 11, 1930, No. 37370. [Class 103 (i).] In an internal expanding or external contracting brake, a backing or support for the friction lining is secured to each metallic shoe or band solely by surface bonding, for example by vulcanization. In one form the backing material 42, as shown in the Figure, is surface bonded to the rims of the shoes 26<1 >and the linings 29 are vulcanized to the backing material. The shoes may be electroplated or otherwise provided with a layer of metal, for example, copper, to which the backing material may be vulcanized. The inner surface of the lining may be coated with a rubber composition prior to vulcanization to the backing which, it is stated, prevents squeaking of the brake.

Title: Improvements in nozzles or jets for liquids

IPC: B05B1/26
Filed: 1968-08-07
Abstract: 1,207,877. Spray producers. HAWK PLASTICS Ltd. 5 Aug., 1969 [7 Aug., 1968], No. 37660/68. Heading B2F. Nozzles for liquids are made of deformable material, and have one or more internal projections 18 that can be displaced, by deforming the delivery portion of the nozzle, from a position in the path of liquid flowing through the nozzle to a position substantially clear of said path or vice versa. The projection(s) may be of triangular pyramidal form and the nozzle may be made of resilient plastics material. Water from a hose passing a constriction at 3 strikes the projection 18 and issues as a spray. On applying pressure to the walls 15, 16 the walls 13, 14 move apart, the projection 18 moves out of the path of the water which then issues as a jet. Alternatively the projections may be mounted on walls 15, 16 whereby pressure converts a jet to a spray.

Abstract: 1314368 Radar BENDIX CORP 6 Aug 1970 [7 Aug 1969(2)] 38058/70 Heading H4D An indicating device 101, Fig. 1, comprises a vessel 12 containing a fluid 14, and a waveguide 16 mounted by means of a plug or guide member 24 on the vessel, with one end immersed in the liquid. This end is short circuited by means of a conductive disc 18, but the liquid may enter freely through slots or holes 32. There is a microwave generator 20 at the other end of the waveguide 16, and a probe 48 projects into the waveguide to sample the electric field intensity and provide an indication on a meter 44. Standing waves are set up within the waveguide and the position of a node relative to the probe, and hence the field intensity which it samples, depends upon the amount and dielectric properties of the liquid within the waveguide. As described with reference to Fig. 1, the density of a liquid is to be indicated, and the waveguide 16 is of co-axial type, with the probe 42 mounted below the surface of the liquid. It is arranged for a node of the standing waves to appear at the probe when the density value is at one extreme of the range to be indicated (Fig. 3, not shown). In another embodiment, for indicating the level of the liquid in the vessel, the probe is positioned above the highest level in the range (Figs. 4 to 6, not shown).
